Probability of Obtaining Both Heads from Two Unbiased Coins
Answer:
When two unbiased coins are tossed, there are four possible outcomes:
- Head - Head
- Head - Tail
- Tail - Head
- Tail - Tail
Since each coin has two possible outcomes (head or tail) and the coins are independent, there are a total of 2 x 2 = 4 possible outcomes.
Out of these four possible outcomes, only one outcome is "both heads" (HH), which means that the probability of obtaining both heads is:
P(HH) = 1/4
Therefore, the correct answer is option 'A'.
